However, operators often encounter the problems that the plugging components on the water softener are easy to separate, so that the whole power-off and salt adding operation is inconvenient, and the valve control components and the salt well components on the water softener are inconvenient to maintain and the like in the process of using the water softener. In order to solve the above problems, embodiments of the present invention provide a water softener as shown in fig. 1 to 10.

As shown in fig. 1 and 2, the water softener according to the embodiment of the invention includes a tank 10, a top cover device, a resin tank 60 and a salt well assembly 90, a receiving chamber 11 is formed in the tank 10, a tank opening 12 communicating with the receiving chamber 11 is provided at the top of the tank 10, the top cover device is mounted at the tank opening 12, and the resin tank 60 and the salt well assembly 90 are respectively mounted in the receiving chamber 11. Here, the inside of the case 10 shown in the present embodiment is used for salt loading, so that the case 10 is also called a salt tank of an existing water softener.

As shown in fig. 3, the header device of the embodiment of the present invention includes a middle frame assembly 20, a first header assembly 30, and a second header assembly 40.

Wherein, the middle frame component 20 is detachably connected with the box opening 12 of the box body 10, the middle frame component 20 is provided with a first through opening 24, the first through opening 24 is used as a salt adding opening of the water softener, and the first through opening 24 is communicated with the accommodating cavity 11.

To facilitate the salting operation, the present embodiment rotatably connects one end of the first header assembly 30 to the center frame assembly 20. In this case, the first cap assembly 30 may also be referred to as a flip assembly, by controlling the flip of the first cap assembly 30 relative to the middle frame assembly 20 to conveniently control the closing or opening of the first pass-through 24 based on the first cap assembly 30.

As shown in fig. 3, the first top cover assembly 30 according to the embodiment of the present invention includes a cover 31 and a crank arm 32, wherein a first end of the crank arm 32 is connected to one end of the cover 31, and a second end of the crank arm 32 is rotatably connected to the middle frame assembly 20.

In this embodiment, the middle frame assembly 20 is provided with a adaptor 34, and the second end of the crank arm 32 is rotatably connected to the adaptor 34. In order to ensure the aesthetic appearance of the crank arm 32, a decoration 36 is provided on the side surface of the crank arm 32, and the crank arm 32 and the decoration 36 are detachably connected by a clamping structure.

In order to avoid the interference between the movement of the crank arm 32 and the middle frame assembly 20, the middle frame assembly 20 is provided with the avoiding opening 27 in this embodiment, at least part of the crank arm 32 is located in the avoiding opening 27, and the adaptor 34 is disposed on one side of the avoiding opening 27.

Here, the present embodiment enables the cover 31 to be turned relative to the middle frame assembly 20 between the first position for closing the first through opening 24 and the second position for opening the first through opening 24 based on the arrangement of the crank arm 32, and ensures that a relatively large turning angle of the cover 31 relative to the middle frame assembly 20 can be achieved.

Further, in this embodiment, the structure of the crank arm 32 may be optimally designed, so that the overturning angle of the cover 31 relative to the middle frame assembly 20 is greater than 90 °, so that the upper side of the first through opening 24 can reach a sufficiently large open space when the cover 31 is in the second position, thereby facilitating the operator to add salt into the box 10 through the first through opening 24.

As shown in fig. 2 and 8, in order to ensure that the cover 31 has a flip angle of greater than 90 ° relative to the middle frame assembly 20, the crank arm 32 of the present embodiment includes a long arm section 321 and a short arm section 322.

The long arm section 321 is arc-shaped, and the short arm section 322 is linear; the first end of the long arm section 321 is connected to one end of the cover 31, the second end of the long arm section 321 is connected to the first end of the short arm section 322, and the second end of the short arm section 322 is rotatably connected to the adapter 34 on the middle frame assembly 20.

Wherein the distance between the second end of the short arm section 322 and the first end of the long arm section 321 is smaller than the distance between the first end of the short arm section 322 and the first end of the long arm section 321, so that the crank arm 32 shown in the present embodiment is similar to a fishhook shape.

Here, the optimized design of the crank arm 32 in this embodiment not only ensures that the cover 31 can reach a relatively large turning angle with respect to the middle frame assembly 20, but also ensures that the cover 31 is as far away from the first through opening 24 as possible when reaching the maximum turning angle, thereby improving the convenience of salt adding operation.

As shown in fig. 4 and 8, the first top cover assembly 30 of the present embodiment is further provided with a stop portion 35, where the stop portion 35 is connected to the crank arm 32, and the stop portion 35 is used to abut against or separate from the middle frame assembly 20.

Specifically, in the present embodiment, the abutment portion 26 is provided on the center frame assembly 20. The stopper 35 is separated from the abutment 26 when the cover 31 is in the first position, and the stopper 35 abuts against the abutment 26 when the cover 31 is in the second position.

Here, the second position of the cover 31 in the embodiment corresponds to the position of the cover 31 when the maximum turning angle is reached with respect to the middle frame assembly 20. For example, the cover 31 may reach a maximum flip angle of 100 ° to 150 ° relative to the middle frame assembly 20.

Since the cover 31 is inclined with respect to the vertical when the cover 31 is in the second position, the cover 31 can be ensured to reach the stress balance state by the mutual abutment of the stopper 35 and the abutment 26, and the cover 31 can be stably maintained in the second position without manual support by the operator, and the state thereof can not be changed any more, and only when the first through hole 24 needs to be closed, the cover 31 is turned over from the second position to the first position by the driving of the operator.

As shown in fig. 4, in order to facilitate control of the tilting angle of the cover 31 relative to the middle frame assembly 20, the stopper 35 in the present embodiment is provided on the outer side surface of the crank arm 32.

Since at least part of the crank arm 32 is located in the escape opening 27 on the middle frame assembly 20, in this embodiment, the abutment portion 26 is provided on the first wall surface of the escape opening 27, and the first wall surface of the escape opening 27 is opposite to the outer side surface of the crank arm 32. Thus, when the cover 31 is in the first position, the stopper 35 is away from the abutment 26, and when the cover 31 is turned in the first rotational direction relative to the middle frame assembly 20 to reach the second position from the first position, the stopper 35 gradually approaches the abutment 26 along with the deflection of the crank arm 32, and when the stopper 35 abuts against the abutment 26, the cover 31 reaches the second position, and the cover 31 cannot be turned further in the first rotational direction.

Preferably, in order to selectively control the maximum turning angle of the cover 31 according to practical needs, the present embodiment is provided with a plurality of mounting positions on the crank arm 32, the plurality of mounting positions are sequentially arranged along the extending direction of the crank arm 32, and the stop portion 35 is selectively detachably connected with any one of the plurality of mounting positions.

In some examples, a plurality of mounting locations may be disposed on the outer side of the crank arm 32, and each mounting location may be a latch slot disposed on the outer side of the crank arm 32, and the latch head is formed on the stop portion 35. After determining the maximum turning angle of the cover 31, the operator can determine the buckling slot corresponding to the maximum turning angle, so that the buckling head on the stop part 35 is directly buckled in the buckling slot corresponding to the maximum turning angle, and the cover 31 can be controlled to reach the required maximum turning angle.

As shown in fig. 3, the flip cover assembly of this embodiment further includes a damper shaft 33, one end of the damper shaft 33 is connected to the second end of the crank arm 32, and the other end is connected to an adapter 34 on the middle frame assembly 20.

The damping shaft 33 may include a first shaft section and a second shaft section, wherein the second end of the crank arm 32 is connected to one end of the first shaft section, the other end of the first shaft section is rotatably connected to one end of the second shaft section, and the other end of the second shaft section is connected to the adaptor 34.

Here, in this embodiment, while the other end of the first shaft section is rotatably connected to one end of the second shaft section, it is also ensured that the contact friction between the other end of the first shaft section and one end of the second shaft section is greater than a preset value, so that when the second end of the crank arm 32 is rotatably connected to the middle frame assembly 20 through the damping shaft 33, it is also ensured that the cover 31 can stay at any desired hovering position during the overturning process.

Further, in order to ensure that the cover 31 can be reliably turned over relative to the middle frame assembly 20, a plurality of crank arms 32 are provided in the present embodiment, the plurality of crank arms 32 are arranged side by side, a first end of each crank arm 32 is connected to one end of the cover 31, and a second end of each crank arm 32 is rotatably connected to the middle frame assembly 20 through a damper shaft 33.

As shown in fig. 8, in order to ensure the structural strength of the cover 31 corresponding to the flip member, the cover 31 in this embodiment includes a panel layer 311 and a support member, and the panel layer 311 is connected to the support member. The support assembly is constructed with a support portion 301, and the support portion 301 is supported at a central region of the panel layer 311.

The panel layer 311 in this embodiment is mounted on the upper surface of the supporting component, and the supporting portion 301 on the supporting component contacts with the middle area of the panel layer 311. The toughened glass has larger structural strength and can be cut into different shapes according to actual requirements, so that the panel layer 311 shown in the embodiment is preferably a toughened glass layer.

Meanwhile, the support assembly shown in this embodiment may be made of engineering plastic or steel having a certain structural strength.

Here, the flap assembly of the present embodiment is applied to a water softener for opening or closing a salt port on the water softener. For example, in the case where the center frame assembly 20 is mounted to the tank opening 12 of the water softener, the flip cover assembly is rotatably mounted to the first through opening 24 of the center frame assembly 20 to open or close the first through opening 24.

Based on the supporting effect of the supporting portion 301 on the middle region of the panel layer 311, the deformation resistance of the panel layer 311 can be increased, and when the middle region of the cover 31 is stressed too much, the middle region of the panel layer 311 can be prevented from being depressed.

Preferably, in order to facilitate assembling the panel layer 311 and the support assembly into a whole, the support assembly in this embodiment includes an inner liner 312 and a support layer 313, wherein the inner liner 312 is sandwiched between the panel layer 311 and the support layer 313, and the panel layer 311, the inner liner 312 and the support layer 313 are sequentially connected.

In the actual assembly process, an adhesive layer may be disposed between the panel layer 311 and the inner liner 312. The adhesive layer is 3M adhesive or PUR adhesive (Polyurethane Reactive, moisture curing reaction polyurethane hot melt adhesive) which is well known in the art.

In order to ensure the reliability of the adhesion between the panel layer 311 and the liner layer 312, the present embodiment may form a groove in a side surface of the liner layer 312 facing the panel layer 311, a portion of the adhesive layer adheres to the groove, and another portion of the adhesive layer adheres to the panel layer 311 when the panel layer 311 is adhered to the liner layer 312. Wherein the depth of the groove can be 0.3-0.5 mm.

Meanwhile, in order to facilitate assembly of the inner liner 312 and the support layer 313, the present embodiment may connect the inner liner 312 and the support layer 313 through a plurality of fastening structures. The buckling structure consists of a buckling block and a buckling groove which can be buckled into a whole.

In one example, the present embodiment may provide a plurality of buckling blocks on a side of the lining layer 312 facing the supporting layer 313, and a plurality of buckling slots on a side of the supporting layer 313 facing the lining layer 312. When the side surface of the lining layer 312 facing the supporting layer 313 is attached to the side surface of the supporting layer 313 facing the lining layer 312, the buckling blocks are buckled in the buckling grooves in a one-to-one correspondence manner, so that the detachable connection between the lining layer 312 and the supporting layer 313 is realized conveniently.

Further, in order to facilitate the formation of a support in the middle region of the panel layer 311, the support layer 313 shown in this embodiment includes a first support platform, where the first support platform is disposed in the middle region of the support layer 313; the inner liner 312 comprises a second support table, which is arranged in the middle area of the inner liner 312; the first support stand is connected to the second support stand, and constitutes the support portion 301 shown in the above-described embodiment.

The first support table and the second support table may be cylindrical, cubic, boss-like, or the like, and are not limited herein.

As shown in fig. 8, the support layer 313 in this embodiment includes a first frame and a first extension rib. The first extending ribs are provided with a plurality of first extending ribs, one ends of the plurality of first extending ribs are respectively connected with the inner side face of the first frame, and the other ends of the plurality of first extending ribs extend towards the center of the first frame and are connected to the side face of the first supporting table located in the middle of the first frame.

Accordingly, the inner liner 312 in this embodiment includes a second frame and a second extension rib. The second extends the muscle and is equipped with a plurality ofly, and a plurality of second extend the muscle one end and be connected with the medial surface of second frame respectively, and a plurality of second extend the muscle the other end and extend towards the center of second frame respectively to be connected in the side of the second brace table that is located the middle part of second frame.

The first frame and the second frame shown in the embodiment are detachably connected through the buckling structure shown in the embodiment, and the first extending ribs and the second extending ribs can be arranged in a one-to-one opposite mode while the first supporting table and the second supporting table are arranged oppositely.

As shown in fig. 5, in practical application, one end of a power adapter of a water softener is provided with a first plug terminal 1001, one end of an internal power line of the water softener is provided with a second plug terminal 1002, and after the first end of the first plug terminal 1001 is plugged with the first end of the second plug terminal 1002 to form a plug assembly 100, an external power source can supply power to the water softener through the plug assembly 100. However, since the socket assembly 100 is generally randomly placed in the water softener, when one end of the power adapter is stressed, the first socket terminal 1001 is easily separated from the second socket terminal 1002, resulting in that the water softener cannot function properly.

For this reason, the installation component is provided on the middle frame assembly 20, and the installation component is used for installing the plug assembly 100, so as to avoid the plug assembly 100 being randomly placed in the water softener, and the first plug terminal 1001 and the second plug terminal 1002 on the plug assembly 100 are separated under the action of external force.

The mounting component may be a binding component, a clamping component, a locking component, etc. which are well known in the art, and is not specifically limited herein.

Here, in order to facilitate the installation of the plug assembly 100, the installation member shown in the present embodiment is preferably the clip assembly 23.

As shown in fig. 5 to 7, in order to solve the problem that the plugging assembly 100 is easy to separate under the action of external force, the present embodiment provides a middle frame assembly 20, wherein the middle frame assembly 20 includes a middle frame 21 and a clamping assembly 23, and the clamping assembly 23 includes a clamping slot 231; the clamping groove 231 is connected with the middle frame 21, the clamping groove 231 is used for storing the plug assembly 100, the clamping groove 231 is provided with a first bayonet 2311 and a second bayonet 2312, and the first bayonet 2311 and the second bayonet 2312 are respectively arranged on groove walls of two ends of the clamping groove 231 along the length direction.

The second end of the first plug terminal 1001 generally has a first connecting line extending toward the power adapter, the diameter of the first connecting line being smaller than the diameter of the second end of the first plug terminal 1001; accordingly, the second end of the second socket terminal 1002 generally has a second connection wire extending toward the internal electrical device of the water softener, and the diameter of the second connection wire is smaller than the diameter of the second end of the second socket terminal 1002.

In practical application, the first connection wire corresponding to the first plug terminal 1001 is inserted into the first bayonet 2311, and the first bayonet 2311 is clamped to the second end of the first plug terminal 1001; the second connecting wire corresponding to the second plug terminal 1002 is inserted into the second bayonet 2312, and the second bayonet 2312 is clamped to the second end of the second plug terminal 1002.

In some examples, the present embodiment may provide that the width of the first bayonet 2311 is smaller than the maximum diameter of the second end of the first plug terminal 1001 and the width of the second bayonet 2312 is smaller than the maximum diameter of the second end of the second plug terminal 1002.

In this way, when the first plug terminal 1001 receives the traction force from the power adapter, the first plug terminal 1001 does not pass through the first bayonet 2311 under the action of the traction force, but the first bayonet 2311 limits the first plug terminal 1001 to move towards the side far away from the second plug terminal 1002, so as to achieve the effect of preventing the plug assembly 100 from being separated under the action of external force.

Accordingly, when an operator carelessly applies a pulling force to the connecting wire of the second plug terminal 1002, the second plug terminal 1002 will not pass through the second bayonet 2312 under the action of the pulling force, but the second bayonet 2312 limits the second plug terminal 1002 to move towards the side far away from the first plug terminal 1001, so as to achieve the effect of preventing the plug assembly 100 from being separated under the action of external force.

As shown in fig. 7, in order to further prevent the first plug terminal 1001 from being separated from the second plug terminal 1002 under the traction force of the power adapter, the clamping assembly 23 in this embodiment further includes a limiting portion 232, where the limiting portion 232 is connected to the middle frame 21; the limiting portion 232 is disposed outside the clamping groove 231 and is close to the notch of the clamping groove 231.

The limiting portion 232 may be a limiting block well known in the art, and a clamping gap is formed between a side surface of the limiting block facing the clamping groove 231 and a groove bottom of the clamping groove 231, and a width of the clamping gap is greater than or equal to a maximum diameter of the first plug terminal 1001.

In practical application, a protrusion is generally disposed at an end of the first plug terminal 1001 away from the power adapter, after the first plug terminal 1001 is installed in the clamping slot 231 and is plugged with the second plug terminal 1002, the limiting portion 232 is disposed between the protrusion and the first bayonet 2311 along the length direction of the clamping slot 231, and the limiting portion 232 is abutted with the protrusion.

Thus, when the power adapter pulls the first plug terminal 1001 under the action of self gravity, the first bayonet 2311 forms a limit on one end of the first plug terminal 1001 close to the power adapter, and the limit portion 232 further forms a limit on one end of the first plug terminal 1001 far away from the power adapter, so that the clamping assembly 23 shown in the embodiment can reliably prevent the first plug terminal 1001 from being separated from the second plug terminal 1002 under the action of the pulling force of the external force.

As shown in fig. 7, in order to facilitate the installation of the plug assembly 100, the clamping groove 231 in this embodiment is provided with an opening 2313, and the opening 2313 is configured on a groove wall of the clamping groove 231 along the length direction, and the opening 2313 is used for the first plug terminal 1001 or the second plug terminal 1002 to pass through.

Specifically, the opening 2313 shown in the present embodiment extends along the length direction of the catching groove 231. In order not to affect the clamping effect of the clamping groove 231 on the whole plug assembly 100, the embodiment provides that the length of the opening 2313 extending along the length direction of the clamping groove 231 is smaller than the length of the clamping groove 231 and larger than the length of the first plug terminal 1001 or the second plug terminal 1002.

In order to avoid affecting the installation of the inverted salt grid 110 in the first through hole 24, the clamping assembly 23 in the embodiment described above may be disposed on the inner wall of the second through hole 25.

In this embodiment, since the first top cover assembly 30 for controlling the opening and closing of the salt adding port and the second top cover assembly 40 for controlling the opening and closing of the maintenance port are both integrated on the middle frame assembly 20, when the water softener is subjected to after-sales maintenance, an operator does not need to consider the sequence of opening the first top cover assembly 30 and the second top cover assembly 40, and only needs to detach the middle frame assembly 20 from the tank port 12, so that the whole disassembly of the top cover device can be realized, the operation is simple and convenient, and the maintenance operation is simplified.

Based on the scheme shown in the above embodiment, as shown in fig. 1, this embodiment also provides a water softener, which includes a tank 10 and a top cover device.

As shown in fig. 1, a housing chamber 11 is formed in the inside of a casing 10 of the water softener, and a tank opening 12 communicating with the housing chamber 11 is formed at the top end of the casing 10.

The top cover device comprises a middle frame assembly 20, wherein the middle frame assembly 20 is detachably connected with the box opening 12, and the middle frame assembly 20 is inclined relative to the bottom surface of the box body 10 along a first direction so as to guide water on the surface of the middle frame assembly 20 to flow into the accommodating cavity 11; the surface of the middle frame assembly 20 is provided with the mounting members shown in the above embodiments, on which the plug assembly 100 is mounted.

Here, the mounting member in the present embodiment protrudes from the surface of the middle frame assembly 20, and the mounting member can prevent water on the surface of the middle frame assembly 20 from flowing onto the plug assembly 100 while mounting the plug assembly 100. After water enters the water softener, water drops attached to the surface of the middle frame assembly 20 automatically flow along the surface of the middle frame assembly 20 under the action of dead weight and flow into the box 10, so that water flow or liquid drops can be prevented from entering the plug assembly 100 as much as possible based on the inclined arrangement of the middle frame assembly 20, and the normal operation and power supply safety of the water softener are ensured.

As shown in fig. 1, the included angle α between the first direction and the bottom surface of the case 10 in the present embodiment is 5 ° to 30 °, for example, the included angle α may be specifically 5 °, 10 °, 20 ° and 30 °, which is not limited herein.

Further, the water softener shown in this embodiment further includes: the first cap assembly 30 and the second cap assembly 40. The first top cap assembly 30 is connected to the middle frame assembly 20, and the first top cap assembly 30 is opposite to the first through opening 24 on the middle frame assembly 20 for closing or opening the first through opening 24; the second top cap assembly 40 is coupled to the middle frame assembly 20, and the second top cap assembly 40 is opposite to the second through opening 25 of the middle frame assembly 20 for closing or opening the second through opening 25. The first through opening 24 and the second through opening 25 on the middle frame assembly 20 are respectively communicated with the accommodating cavity 11, and the middle frame assembly 20 is detachably connected with the box opening 12.

Since the first and second header assemblies 30 and 40 are mounted on the middle frame assembly 20, respectively, when the middle frame assembly 20 is disposed obliquely, the first and second header assemblies 30 and 40 are also disposed obliquely correspondingly, so that the entire header assembly is disposed obliquely. In practical application, if water drops are attached to the outer surface of the top cover device, the water drops can flow automatically along the outer surface of the top cover device under the action of dead weight, so that the water drops can be prevented from flowing into the box 10.

Meanwhile, the top cover device is arranged in an obliquely distributed arrangement structure, so that the attractiveness of the whole structure of the water softener is ensured. When the water softener is actually placed indoors, the water softener can be arranged near the wall of one side of the first end of the middle frame assembly 20, so that the arrangement of the water softener and the indoor environment are unified.

Here, since the first through opening 24 is a salt adding opening and the second through opening 25 is a maintenance opening, the vertical height of the center of the second through opening 25 with respect to the bottom surface of the case 10 may be set to be greater than the vertical height of the center of the first through opening 24 with respect to the bottom surface of the case 10. Through so setting, this embodiment has reduced the setting height of adding the salt mouth, and operating personnel is convenient for directly add salt to box 10 through adding the salt mouth, and its easy operation is convenient.

In some embodiments, as shown in fig. 3, to facilitate maintenance of the valve control assembly 80 at the top end of the resin tank 60, the present embodiment removably connects the second header assembly 40 to the middle frame assembly 20.

In this embodiment, the second top cover assembly 40 and the middle frame assembly 20 may be connected by a fastening structure. Specifically, in this embodiment, a latch block may be disposed on the second top cover assembly 40, and a latch slot adapted to the latch block may be disposed on the middle frame assembly 20. When the second top cover assembly 40 is installed, the buckling blocks of the second top cover assembly 40 are directly buckled in the buckling grooves on the middle frame assembly 20, and the operation is simple and convenient.

In some embodiments, at least one of a human-computer interaction module and a display window is disposed on the second top cover assembly 40.

Here, the man-machine interaction module shown in this embodiment is used for an operator to input relevant control instructions to the water softener and display relevant operation parameters of the water softener. The human-machine interaction module can be any one or a combination of a plurality of digital displays, touch screen controllers and physical keys.

Meanwhile, in order to facilitate the operator to directly observe the failure state of the valve control assembly 80 at the top end of the resin tank 60, the present embodiment may also provide a display window on the second cap assembly 40. For example, in the present embodiment, a through hole may be formed in a middle region or an edge region of the second top cover assembly 40, and a transparent glass or a transparent plastic plate may be mounted at the through hole, and the display window shown in the present embodiment may be formed of the transparent glass or the transparent plastic plate.

Thus, the second cap assembly 40 may also be referred to as a display cap assembly based on the functions of the second cap assembly 40 as a data display and viewing window in practical use.

In the related art, when fixing the resin tank 60 of the water softener, the bottom end of the resin tank 60 is generally mounted to the bottom end of the case 10, and the top end of the resin tank 60 is fixed by the fixing plate 50 after passing through the inner frame 70.

However, in practical applications, the case 10 has a certain deformation due to the processing difference, and the resin tank 60 also has a difference in height dimension of the resin tank 60 due to the processing or assembling deviation, and the fixing of the resin tank 60 by the conventional fixing plate 50 lacks a certain flexibility, so that it is difficult to satisfy the installation of the fixing plate 50 and the fixing requirement of the resin tank 60.

As shown in fig. 9 and 10, in order to solve the above-mentioned problem, the present embodiment further provides a fixing plate 50, wherein the fixing plate 50 includes a flexible plate body 51, a first opening 52 and a plurality of notches 53 are configured on the flexible plate body 51, the plurality of notches 53 are respectively arranged along the circumferential direction of the first opening 52, and the opening ends of the notches 53 are formed on the opening wall of the first opening 52.
